    摘要
  • 摘要: 泥石流灾害的防治通常采用“稳、拦、排”的基本模式，但对于不具备排导条件的泥石流治理方法，仍在探索之中。本文以阿勒泰布尔津县科克逊泥石流为例，对排导受限条件下的泥石流防治模式进行了探索性的分析研究，提出了“上游拦挡物源、中游稳固沟道和消能、下游综合排导”泥石流治理新模式。该模式在稳定和拦截泥石流物源的基础上，充分利用下游地形地质条件，在下游沟口地形开阔处修建拦水堤坝，坝前设置渗水区，拦截和储存水体，借助该区地层良好的渗透性，使临时储存的水体快速下渗转化为地下水进行排泄，从而有效达到治理泥石流灾害的目的。本文以新疆布尔津科克逊泥石流为例，系统分析了研究区地形地貌、水文、工程地质条件、下游堆积区地质结构等，优化了工程布局和结构设计，通过现场工程应用验证了新模式的可行性和有效性，并根据不同地质条件、气候特征、社会经济情况等提出了相应的适应性调整措施，提高泥石流防治的长期有效性，成果可为排导困难区域的泥石流防治提供借鉴。
    Abstract: Debris flow is a serious natural hazard that requires effective prevention and control measures. However,the conventional mode of "stability,blocking and drainage" is not applicable for debris flow without drainage conditions. This paper proposes a new debris flow control model of "upstream blocking material source,middle stream stable channel and energy dissipation,and downstream comprehensive drainage". This model utilizes the downstream topography and geological conditions to create a seepage area and a water barrier that can infiltrate and drain the water bodies of debris flow,thus reducing the disaster risk. Taking Koxun debris flow in Burjin County of Altai,Xinjiang as a case study,this paper analyzes the characteristics and parameters of debris flow gully,optimizes the engineering layout and design,and verifies the feasibility and effectiveness of the new model through field application. The paper also discusses the adaptability and applicability of the new model for different situations and provides reference for similar debris flow prevention and control in Xinjiang and other places.
